Hello Chris,
The ATSC EPG is sent via the ATSC PSIP protocol. I do not know of any
tools currently available to extract the information. MeTV has a
working implementation (with some bugs I have seen), and I was looking
at getting it to work in Kaffeine at some point.
The spec is freely available here:
http://www.atsc.org/standards/a_65cr1_with_amend_1.pdf
If you have any questions, feel free to drop me a line.
Cheers,
Devin
